Today we will be learning: how to compare and order fractions how to use, read and write words to do with fractions.
3
Mental Activity We are going to practise doubling. Work out the answer before it appears. Double 11 22
4
Double 12 24 Double 14 28 Double 17 34
5
Now we are going to practise multiplying by 4 quickly. We do this by doubling then doubling again. Work out the answer before it appears. 11 x 4 44
6
9 x 4 36 12 x 4 48 20 x 4 80
7
15 x 4 60 25 x 4 100 14 x 4 56
8
Main Activity Today we are going to learn to order fractions.
9
Here is a piece of paper. 2 If it were folded once in the middle, how many equal parts would there be?
10
What would each part be called? 2 1212 1212 One half or 1212
11
If it were folded in half again, how many equal parts would there be? 2 1212 1212 4
12
What would each part be called? 2 1212 1212 4 One quarter or 1414 1414 1414 1414 1414
13
If the paper were folded in half again, how many pieces would there be? 8
14
What would each piece be called? 1818 1818 1818 1818 1818 1818 1818 1818 One eighth or 1818
15
Here are two fractions. 1212 2828 Which one do you think is bigger? Why?
16
1212 2828 One half is greater than two eighths. 1212 2828
17
1212 2828 This symbol means “is greater than”. The big end faces the biggest number.
18
Group Work Fold a strip of paper in half, then in half again and so on. Complete a chart to show the fractions that you have made. Make up some equivalent fractions. Order fractions using ‘greater than’ and ‘less than’ symbols.
